people here think like pre-schoolers.
chess doesnt force you to be smart, as in principle, anyone intelligent enough to learn the rules (a very low bar) can play, but they are plenty of things going on
.statistically, people are more likely to keep doing something they are half proficient at, and chess ability is correlated to constellation of traits related to it (functional memory, long term memory, concentration etc). You cant for example, have a high iq if your concentration is very bad. There's a minimal threshold .
add a minimal level of chess ability beyond the causal level and the pruning based on iq starts picking up steam.
if you understand what "Average" mean, you understand, you can make both the median and mean higher by artificially removing the lower tail of distribution and chess, especially when played well does that. Get a bell curve, and remove most people on the lower tail, and the average increases substantially without there being more geniuses added.
this is not an english class, no one cares if it is their or his/her.. why did it have to take pages? we already understand what it means.. oh but it is too important to feel "right".. right? stop spamming the thread, already reported
